Elevator arranged in bottomless pit of old building

Abstract

The invention discloses an elevator arranged in a bottomless pit of an old building. The elevator comprises a bottom plate, wherein buffer piers are fixedly arranged at the two sides of the upper endof the bottom plate separately; a car frame lower beam is fixedly arranged at the upper end of the bottom plate between the two buffer piers; the two sides of the car frame lower beam are fixedly equipped with first guide boots separately; a car is fixedly arranged at the upper end of the car fame lower beam; the two sides of the car are movably equipped with car pulling strips separately; a dooropening rack is fixedly arranged at the upper end of the car; a fan frame is fixedly arranged at the upper end of the door opening rack; and the two ends of the two buffer piers are fixedly equipped with polyurethane buffers separately. The polyurethane buffers are arranged, so that the collision risk which possibly occurs is effectively reduced; the affecting and reinforcing problem, caused by digging an elevator shaft, for the original residential foundation is avoided through an elevator bottom pit; and meanwhile, the materials can be placed at the upper ends of the elevator buffer piers, and are conveniently replaced, so that the elevator is safer and is more convenient for maintenance in comparison with a way that the original elevator shaft has a bottom pit.

Description

technical field [0001] The invention relates to the field of adding elevators to bottomless pits, in particular to an elevator adding to bottomless pits in old buildings. Background technique [0002] Elevator refers to the permanent transportation equipment that serves several specific floors in the building, and its car runs on at least two rigid rails that are perpendicular to the horizontal plane or at an inclination angle of less than 15° from the plumb line. There is also a step type, and the tread plate is installed on the crawler belt to run continuously, commonly known as an escalator or a moving walk. Fixed lifting equipment serving specified floors. A vertical elevator has a car running between at least two vertical or inclination angles of less than 15° rigid guide rails. The size and structure of the car are convenient for passengers to enter and exit or to load and unload goods. It is customary to use elevator as a general term for vertical transportation in...
